Probably highest on my wishlist for more realism in FPS games is pretty simple: add wind. While I do delight in sniping the heck out of an opposing team, the thing that gets me is that sniping is so trivially easy in these games due to the fact that no external factors really exist. If you're strafing with machine guns, you obviously lose precision, but in most of these games you just crouch or get prone and have 100% accuracy. If you add wind, I really feel like that might be enough to turn it into a more skilled game, since you COULD die instantly from anywhere, but a sniper can also give away his position without killing you.

A price tag.

Perhaps that's part of the compatibility... it now accurately ignores everything in tags, even if it's a legacy conditional comment. Sure, they may have been a great tool to make cross-browser compatibility a little easier, but if makes IE8 deviate from the spec, then maybe it isn't that important to the IE8 team.

Well I guess a massive penis could be rather threatening, but how would the terrorists make use of my terrifyingly huge penis? Write a message on it? Or maybe they're just trying to get the point across that they have to ability to produce Wangs of Mass Destruction?

I believe you meant, Weapons of Ass Destruction.
